To all whom it may concern:

Be it known that l, GI-IARLES P. S'rANnoN, a citizen of the UnitedStates, residing at Lynn, in the county of Essex and State ofMassachusetts, have invented an Improvement in Knife-Mountings forSole-Rounding' Machines, of which the following description, inconnection with the accompanying drawings, is a specification, likecharacter-son the drawings representing like parts. v

The invention to be hereinafter described relates to solo roundingmachines, and more particularly to the knife mounting in such machineswhereby the sole is trinnned or out to the pattern, as usual in thisclass of inecliines.

It-ha-s been proposed heretofore to fixedly mount the knife or cutterupon :1 plate which was itself adjustable, so to czirry the cutting edgeof the knife into proper relation with the axis of support or the knifecarrier As will be readily apparent from such construction, the knifewas not adjustable independent of esrry ing plate toward and from theaxis of the knife carrier louse.

1n the present invention the aims and purposes have been to provide aconstruction whereby the knife or cutter might be readily adjustedindependently of adjacent parts, in order to bring the cutting edge intoproper POSilJ-l0l1,,21ll as will hereinafter more fully appear inconnection with the follow ing description and accompany in drawings ofone form of means for carrying the invention into pructicul effect.

In the drawin s: FHYIII'Q 1 is u detached detail View showing the knifemounting end the felulion of the knife to the patterns or clumps whichhold the sole to be 'lrinnncd; Fig. 2 is u detail plun VlGW oi the knifeand mounting indicated in Fig. i; Fig. 3 is it section on the line 3--3of Fig; 1, the lower oortion of said section being broken away; lig. iis a detail perspective view of the knife; Fig. 5 is a detailperspective view of the knife washer; and Fig. (5 is a detailperspective view of the knife carrier block.

Referring more particularly to Figs. 1

and 2 of the drawings, the knife carrying I arm 1 is of usualconstruction and has piv- Otally mounted thereon the knife carrier block2, said block being provided with lugs 4: 5 F 6 for receivinp' u in 6 Ei 2 "9. w 7 0 CD 9 7 c 1 tin which serves as the pivotal support connecting the carrier block 2 with the arm '1, as wi l be readily understood,the construction being such that the block 2 may swing upon its pivotalconnection with the arm 1. The upper portion oi the block 2 is providedwith u transversely extending shoulder 7, Fig. 6, forming shove the lugi a recess 8 for the reception of the knife and knife washer, us willpresently appear.

The knife carrier block 2 is provided with a straight bearing surface 9against which the s :lece 1.0 ol 'u washer ll, Figs. 2, 3 and washerbeing preferably pro vided near its lower portion with an offset orextending lip portion lladupted to engage a corresponding undercutportion 18 in the block .2 Figs. and G, the lower face of the portion 12being adapted to slide on the oppo o hoe portion 01": the carrier block,as will be readily apparent.

The carrier block 2, near-its upper portion, is provided with islet 14,end the knife washer 1 is provided with a, corresponding slot 15, saidslots being for the purpose of receiving eknife clumping screw 16 Fig.3, us ,will hereinafter more fully uppeer.

The knife ispreiin'ubly formed as indicuted in Fig. 4 and comprises abase portion hev n corrugations or like projections and recesses l8 inone face thereof, said corrugations 18 being adopted to engage likecorrugations 19 in the face of the knife wsshcrll, as imlicuted in Figs.2, 4t and. 5. The knife hose 1? is also provided with a screw-tine .dedaperture or recess 20, adepted to receive the correspondinglyscrewthreuded end 21 of the screw 16 for holding the knife indiriduullyin its adjusted position. Projecting upward from the knife hose 1! the ke blade or cutter 22, the edge c which is adopted to act upon the sole Sheld between the clamps or patterns P, Fig. 1.

From the construction thusferdescribed it will be uppurent than, uponloosening the screw 16, the knife may be readily unchnnped andreudjustcd with relation to the knife washer 11 to bring into engagementother corrugated ortions of the co-ecting surfaces of the knifebese andknife washer, and. that,.upon setting up the screw 16 and bearing theknife firmly against the knife washer, the parts may be held in theirreadjusted position. It will be noted that the knife washer 11-is not acarrier for the knife but rather an interposed washer havingcorresponding corrugated or projecting portions on its face which engagelike corrugations or projecting portions on the adjacent face of theknife base, the purpose being to maintain the knife in proper adjustedand vertical position. By reason of the extended bearing portion 12 ofthe knife washer, all strain which is placed upon the knife or cutter 22during the cutting" operations is transmitted to the knife carrier blockand the knife and washer are thus maintained in their proper verticallydisposed position with relation to the knife carrier block.

The knife carrier block is provided with an interiorly screw-threadedrecess 24 which is engaged by an'adjusting screw 25, Figs. 1 and 2, theflanged head portion 26 of E which is adapted to engage the rearwardlyprojecting end 27 .of the knife washer 11, the construction being suchthat the flanged head portion of the screw 25 serves to hold the Washerin position, in addition to the clamping action of the knife clampingscrew 16.

By making the knife'washer 11 independent of the knife, and the latteradjustable to ,carry the knife edge into proper position with respect tothe axis of support of the knife carrier block independently of anymovement of the knife washer, it will be obvious that the knife may bereadily removed for the purpose of grinding and be adjusted,irrespective of any adjustment of the knife washer. Likewise, by havingthese parts ind pendent of each other and the knife .washer interposedbetween the knife base and the carrier block, different characters ofknife washers, both as to size and disposition of the corrugations inthe surface thereof, may be readily substituted the one for the other inorder to enable the knife edge to be properly positioned with respect tothe axis of the knife carrier block. For

instance if it be desirable to adjust the cutting edge 23 of the knifeoutward from the carrier block, or to the left Fig. 3, it is onlynecessary to substitute for the knife washer another of somewhat greaterthickness, and if. it be desired to give greater nicety of adjustment ofthe knife edge 23 toward or from the axis of the carrier block, it isonly necessary to provide a knife washer and knife base with thecharacter of corrugations or projections and depressions suitable tothis end, as will be readily understood by those skilled in the art.

In order that the knife carrier block, which as usual is spring pressedtoward the work supports or patterns P, P, may have -a proper bearingsurface against one of these work supports or patterns, a bearing spring28 is provided, Fig. 2, said spring being clamped in place by a properclamp ing screw 29 and the end portion of'said spring being carriedaround, indicated in Fig. 2, in front of the knife base 17 \Vhat isclaimed is:
